Definitions

  • the invention described herein relates to video recording.
  • VCR video cassette recorder
  • PVR personal video recording
  • Hard disk 110 is used to record video information.
  • Hard disk 110 includes integrated drive electronics (IDE) 120.
  • IDE 120 is a hardware interface used to connect a peripheral device (i.e., hard disk 110) to external logic.
  • hard disk 110 is connected, via IDE 120, to set-top box logic 130.
  • Set-top box logic 130 decodes a cable signal and accepts other signals corresponding to user inputs.
  • Set-top box logic can be implemented as one or more integrated circuits. Note that information passing between set-top box logic 130 and IDE 120 typically passes through a peripheral component interconnect (PCI) bus 140.
  • PCI peripheral component interconnect
  • IDE 120 is collocated with hard disk 110, remote from set-top box logic and communications between IDE 120 and set-top box logic 130 necessarily pass through PCI bus 140.
  • PCI bus 140 PCI bus
  • integrated drive electronics are incorporated in the set-top box logic. This allows the set-top box logic to communicate directly to a hard disk, so that the intervening PCI bus becomes unnecessary.
  • FIG. 1 is a block diagram showing the interconnection between set-top box logic and a hard disk, wherein the hard disk includes integrated drive electronics.
  • FIG. 2 is a block diagram showing the integration of integrated drive electronics in the set-top box logic, according to an embodiment of the invention.
  • FIG. 3 illustrates set-top box logic in greater detail, according to an embodiment of the invention.
  • integrated drive electronics are incorporated in the set-top box logic. This allows the set-top box logic to communicate directly to a hard disk, so that the intervening PCI bus becomes unnecessary.
  • FIG. 2 illustrates the system of the invention generally.
  • Hard disk 210 is shown in communication with set-top box logic 230.
  • set-top box logic decodes a cable signal and accepts other signals corresponding to user inputs.
  • Set-top box logic can be implemented as one or more integrated circuits.
  • Set-top box logic 230 includes IDE 220.
  • IDE 220 represents the interface to hard disk 210. Because IDE 220 is incorporated in set-top box logic 230, information passes directly between set-top box logic 230 and hard disk 210 need not pass through a PCI bus.
  • FIG. 3 illustrates set-top box logic 230 in greater detail.
  • Set-top box logic 230 includes IDE 220.
  • IDE 220 is in communication with hard disk drive 210.
  • IDE 220 receives control and configuration information from a central processing unit (CPU) 310.
  • CPU central processing unit
  • IDE 220 is also connected to memory controller 350.
  • Memory controller 350 allows IDE 220 to communicate as necessary with external memory 340.
  • Set-top box logic 230 can be implemented as one or more integrated circuits.
  • IDE can be used for memory devices other than a hard disk, such as a tape drive or a CD ROM drive.
  • the set-top box may use a video memory medium other than a hard disk, provided that the video memory medium has sufficient speed and capacity.
  • the invention described herein can be used in any context where IDE is necessary to allow set-top box logic to access a video memory medium.
